1 REPAIR PATCH FOR STEAM PIPES.

Application filed July 1, 1926.v Serial No. 119,934.

is toprovide a device of this character which when once positioned, willbe held in its position on the pipe, eliminating any possibility of thesame being accidentally displaced.

A still further object of the invention is to provide a removable curvedplate used in connection with a curved plate carried at one end of ayoke, the first mentioned'curved plate being provided with cut outportions defining shoulders between which the yoke is held, to lock thecurved plate to the yoke, against movement longitudinally of the pipe onwhich the device is positioned.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the 1 invention herein disclosed, may be made within thescope of what 1s claimed, WlthOUtdeparting from the spirit of theinvention.

Referring to the drawing:

Figure 1 is a sectional view through a de- 7 vice constructed inaccordance with the in vention, showing the same as positioned on apipe.

Figure 2 is a side elevational view thereof.

Figure 3 is a side elevational view illustrating a modified form of theinvention.

Referring to the drawing in detail, the device includes anelongatedcurved plate 5 formed with a yoke 6 disposed substantially intermediatethe ends thereof and extended from one of the side edges of the plate.

i As shown, this yoke is curved inwardly so that the outer end thereofwill overlie the central portion of a pipe to which the device issecured.

The yoke is provided with a suitable threaded opening for the receptionof the threaded bolt 7 which is formed with a head 8 to receive a wrenchor similar tool, whereby the bolt may be secured to hold the de ice inposition on a pipe.

Cooperating with the curved plate 5 is a removable curved plate 9 whichhas cut out portions 10 formed adjacent to the edges thereof, which cutout portions define shoulders 11 between which theyoke 6 is positionedupon positioning the device on a pipe. Thus it will be seen that theseshoulders will act to prevent movement of the removable curved plate 9,with'respect to the yoke, to insure against accidental displacement ofthe curved plate to loosen the device.

The bolt 7 is of a length to engage the curved plate 9 as shown byFigure 1, so that when the bolt is properly positioned, the curved plate9 will be securely held against the pipe to which it is secured.

It is contemplated to employ a packing member such as a length of rubberindicated at 12, which is positioned over the break in the pipe beingrepaired, so that when the curved plates are clamped on the pipe, theybreak in the pipe will be temporarily closed, until the proper permanentrepairs may be made.

In the form of. the invention as illustrated by Figure 3, the curvedplates are elongated and are provided with yokes corresponding with theyokes 6 at opposite ends of the curved plate 13, the yokes in thisshowing being indicated at 14. Threaded bolts 15 are also employed inthis showing, for engagement with the curved plates 16 to clamp thecurved plates in position.

The construction shown by Figure 3 is especially adapted for stoppingthe flow of steam or water wherein the pipe is cracked or broken for anappreciable distance.

From the foregoing it will be seen that'due to this construction, abreak or crack in a pipe may be readily and easily repaired temporarily,thereby insuring against the flooding or a room or building in which thebroken pipe occurs.

I claim:

1. In a device of the character described,

a curved plate, a yoke formed integral with the curved plate and havinga threaded opening at its outer end, a removable curved plate having cutout portions formed in its edges and defining shoulders, the removablecurved plate adapted to be positioned to cause the yoke to be heldbetween the shoulders, and a bolt adapted to extend through the threadedopening to engage the removable curvcd plate to clamp the curved platesto a pipe.

2. In a device of the character described,

a curved plate, a yoke forming a partof the curved plate, said yokehaving a threaded opening, a removable plate cooperating with the firstmentioned plate to clamp a pipe therebetween, means forming a part ofthe removable curved plate and engaging the yoke to prevent lateralmovement of the removable cnrved plate, and bolts passing through thethreaded openings to engage the removable curved plate and hold the sameto a pipe.

In testimony that I claim the foregoing as my own, I have hereto afiixedmy signature,

CYRUS J. RYAN.
